Cannula anchor
First Claim
Patent Images
1. An anchor sheet for use with a cannula that is adapted to be inserted within the abdominal cavity of a patient during a laparoscopic surgical procedure, the cannula having an anchor body attached thereto, the anchor body having a distal surface,the sheet comprising:
- first and second major side surfaces and surfaces defining a hole extending between the first and second major side surfaces which afford passage of the cannula,the second major side surface having an adhesive adhered thereto for removably adhering the sheet to the skin of the patient, andan attachment means, associated with the first major side surface, for attaching the sheet to the distal surface of the anchor body, wherein the attachment means is a releasable and reusable attachment means that affords attachment of the sheet to the distal surface of the anchor body, a subsequent release in which the distal surface of the anchor body is spaced from the sheet, and then a subsequent attachment of the sheet to the distal surface of the anchor body.

Abstract
An anchor sheet and anchor body for holding a cannula within the abdominal cavity of a patient is described. The cannula is used during a laparoscopic surgical procedure. The anchor sheet and anchor body assist in holding the cannula in a preferred orientation relative to the abdominal cavity. An attachment mechanism such as a hook and loop fastener may be utilized to connect the anchor sheet to the anchor body.

10. An anchor body for attachment to a cannula that is adapted to be inserted into the abdominal cavity of a patient during a laparoscopic surgical procedure,
the anchor body comprising: -
a sleeve portion having proximal and distal surfaces, surfaces defining a through passage for receiving the cannula, said surfaces defining the through passage opening onto the proximal and distal surfaces, a locking cam, and means mounting the locking cam for movement relative to the sleeve portion between a release position which affords relative movement between the sleeve portion and cannula while the cannula is within the through passage, and a locking position in which movement of the sleeve portion relative to the cannula is restricted and in which the cannula is firmly attached to the anchor body, wherein the anchor body is adapted to be used with an anchor sheet that is attached to the skin of a patient and which has a first major side surface opposite the skin of the patient, and the anchor body comprises attachment means, associated with the distal surface, for attaching the anchor body to the first major side surface of the anchor sheet, wherein the attachment means is a releasable and reusable attachment means that affords attachment of the sheet to the distal surface of the anchor body, a subsequent release in which the distal surface of the anchor body is spaced from the sheet, and then a subsequent attachment of the sheet to the distal surface of the anchor body. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
